' 8 claims. (Cl. zzosacl This invention relates to a cap retainer for tubes and has for an "object to provide a simplified means for retainingthe cap of collapsible tubes, bottles and other containers,'in a closed position on the container or;in a retracted position out of the'way of the user, and which may be moved with minimum manual effort from one position to the other. v Y Y r A further object is to provide' apparatus of this character'whichwill" beformedof a few strong, simple and'durableparts, which will .be and which will not easilyget out of order. i

With theabove and 'otherobjects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications maybe resorted to within the scope of the appended claims without departing from'thespirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming a part of this specification:

Figure 1 is a side elevation of a cap retainer, constructed in accordance with the invention, applied to a collapsible tube. 4

Figure 2 is a view in elevation, taken at an angle of ninety degrees from that shown in Figure 1,

and showing the cap retainer in dotted lines in retracted position.

Figure 3 is a cross sectional view taken on the line 33 of Figure 1. 1

Figure 4 is a side elevation, partly in section, showing a modified form of cap retainer.

Figure 5 is a cross sectional view taken on the line 5--5 of Figure 4.

Figure 6 is a side elevation of the cap retainer applied to a fabric or Cellophane tube.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, I 0 designates a tube of the dispensing type formed of soft metal and adapted to be collapsed for dispensing the contents. The tube is provided as is conventional with a threaded neck upon which the cap I l is engaged to seal the contents air tight. For preventing the loss of the cap, the present invention provides the cap II with a stem I2 disposed centrally on, and en'- tending upwardly from the cap, the stem being formed integral with a knurled disk l3 through the medium of which the cap may be screwed onto and off of the threadedneck of the tube and through the medium of which the cap may be retracted from the'tube and disposed against as shown inFigure 2 when it is desired to dispense the contents of the tube. The cap, the stem. and the knurled disk are formedintegrally.

A disk l4 of any suitable materiaL'such as fibre for example,is mounted on the stem'between the The'diskll is' cap II and the knurleddisk l3. substantially oval in contour and is provided on its transverse shortdiameter with a slot. l5, see Figure 3, to'rotatably receive the stem l2.

The tube H1 in the form of the invention' shown in Figure 1 is provided on itsconical shoulder with downwardly and-outwardly extending lugs by turning the knurled disk I3, the cap to be swung to the dotted line position shown in Figure 2 against the side of the tube, out of the way of the user when the contents are being dispensed, the elasticity of the rubber band holding the cap in theretracted position until it is desired to apply the cap again to the tube.

A modified form of the invention is shown in Figures 4 and 5 in which the cap l9, stem 20, disk 2|, fibre disk 22, and tube 23 are the same as previously described but in this form of the invention the downwardly and outwardly extending lugs 24 are formed on the body of the tube instead of on the shoulder. Also in this formsof the invention the endless rubber band 25 is not disposed astride of the stem 20 but one side of the band is engaged against the side of the stem and the same side of the band passes through the notches 26 in the disk 22, see Figure 5, and then is engaged underneath the lugs 24 while the other side of the band is directed around the curved wall of the tube 23 in alignment with the lugs 24. Thus thedisk 22 is held assembled with the stem 20 and at the same time when the cap is unscrewed from the tube the cap may be retracted to released position against the tube and will be yieldably held in released position by the resiliency of the rubber band.

Another modified form of the invention is shown in Figure 6 in which thetube 21 is formed of fabric material or Cellophane material. In

this form of the invention the cap 28, stem 29, r

knurled disk 30, and fibre disk 3| are the'same the. side of the tube in an out of the way position as heretofore described. In this form of the in- I tion,

vention the rubber band 32 is engaged upon the top surface of the fibre disk 3| thence directed through the oppositely disposed notches in the; fibre disk, and the ends of the band are secured to the tube 21 by strips of adhesive tape 33, ad-
